DEVICE FOR PREVENTING TREMULOUS VIBRATION 0F SAW-GATES..

Specification of Letters Patent No. 22,892, dated February 8i, 1859.

To all whom it may concern.

Be itl known that I, DAVID REYNOLDS, of Ogden, county of Henry, and State of Indiana, have invented a new `and Improved Mode of Preventing` the Saw-Sash from Trenibling lVhile in Motion in the Saw- `Mill; and I do hereby declare that the following is a full and exact description thereof, reference beingl had to the accompanying drawings and to the letters of ref,- erence marked thereon.

The nature of my invention consists in securing to the framework in which the saw sash is worked a straight bar of iron, wood, or other metal as near the saw as possible and near the middle of the lower part of the sash and passing through boxing, which fits it accurately, and when the sash plays up and down in the slides at the sides, or on the fender posts, this straight bar prevents the saw being thrown backward and forward by the operation of the pitman it therefore cuts to much better advantage. n

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

Figure l represents a perspective view of my improvement set in a frame which is construct-ed similar' to any saw mill frame.

bar D passes as also seen in Fig. 2. F F- are two pieces of timber secured to the frame to which is attached the rod or bar D firmly. They are also shown in Fig. 2. G is the saw pitman as seen in Figs. l and 2. H is the crank to which the pitman is attached. I is the shaft; J J the bearings for the shaft, to which the driving power may be att-ached.

Fig. 2 represents a sectional drawing as referred to above showing the sash, the pitman guide rod and its boxing with the two pieces of timber F, F.

What I claim as my invention and desire to secure by Letters Patent is- Combining the guide bar D and boxing E with the sash saw and fender pos-ts for the purposes set forth and substantially as above described.

DAVID REYNOLDS.
